I heard a lot about that car.. and some of it was about how troubled it was. There was a huge post in a forum a while back from Graham (he talks on this board!) that bought one. After he finished the car, he showed at a various shows and left people who saw it awe struck. He went on to say that the kit was totally garbage and that just about every part of it had to be reworked or completely redone by him; to the extent that only a few, if any of the parts were actually sourced from kraftwerkz.

but as far as the company goes, didnt they try to sell the molds and the rights to the car? They probably did go out of business!
